Answer:

dang, you are really trying to get everyone to do your heavy lifting lol.

I'll do coal. and maybe a little more.

Explanation:

Coal What is it?

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.

Coal How we obtain it:

Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

Coal Pros:

Coal is plentiful in many places and it is easy to access through mining, so people rely on it to produce energy. Coal is easy to store. Once it is mined it can be safely stored with no hazard of fire or explosion like there is with gas or oil. It is relatively easy and inexpensive to convert coal into energy.

Coal Cons:

Coal is nonrenewable.  Coal contains the most CO2 per BTU, the largest contributor to global warming.  Severe environmental, social, and health, and safety impacts of coal mining.  The devastation of the environment around coal mines is heavy.  High cost of transporting coal to centralized power plants. Coal is really dirty and not good.

Solar What is it?

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.

Solar How we obtain it:

Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.

Solar Pros:

It's clean energy. Solar power is pollution-free and causes no greenhouse gases to be emitted after installation.  It has reduced dependence on foreign oil and fossil fuels.  It is renewable clean power that is available every day of the year, even cloudy days produce some power.  It gives a return on investment unlike paying for utility bills.

Solar Cons:

Solar doesn't work at night. Solar panels are not attractive. You can't install a home solar system yourself. My roof isn't right for solar. Solar hurts the environment. Not all solar panels are high quality.

Answer:

0.0124 AU

Explanation:

Ganymede takes 7.15 Earth days to orbit Jupiter. Ganymede is measured to be 7.1 X 10⁻³ AU from Jupiter’s center.

We need to find how far away is Callisto from the center of Jupiter if a second moon of Jupiter, Callisto, takes 16.69 Earth days to orbit Jupiter. Let it is r₂. Using third law of Kepler.

\(T^2\propto r^3\)

i.e.

\((\dfrac{T_1}{T_2})^2=(\dfrac{r_1}{r_2})^3\\\\\dfrac{r_1}{r_2}=(\dfrac{T_1}{T_2})^{2/3}\\\\r_2=\dfrac{r_1}{(\dfrac{T_1}{T_2})^{2/3}}\\\\r_2=\dfrac{7.1\times 10^{-3}}{(\dfrac{7.15}{16.69})^{2/3}}\\\\r_2=0.0124\ \text{AU}\)

So, Callisto is 0.0124 AU from the center of the Jupiter.

If  a fashion designer decides to bring out a new line of clothing that reflects the longest wavelength of visible light, the articles of clothing would appear red to the human eye.

Visible light is a type of electromagnetic radiation that is visible to the human eye. It is made up of different wavelengths, and each wavelength corresponds to a different color. The longest wavelength of visible light is red, which has a wavelength of approximately 700 nanometers.

When light strikes an object, some of the wavelengths are absorbed by the object, and others are reflected. The wavelengths that are reflected determine the color of the object that we see. In the case of red clothing, the material is reflecting the longest wavelength of visible light, which is why it appears red to our eyes.

Different colors can have different psychological effects on people. For example, red is often associated with passion, energy, and excitement. It can also stimulate the appetite and increase heart rate. These effects are often used in marketing and advertising to influence consumer behavior.

In summary, if a fashion designer decides to bring out a new line of clothing that reflects the longest wavelength of visible light, the articles of clothing would appear red to the human eye. This color choice can have a powerful impact on the viewer's emotions and behavior.

The laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium.

The thickness of the shifter is given as t = λ / 2n.

The given equation of the phase of light of wavelength λ traveling through a shifter with a refractive index n is given by: Øs = 2πntλ-1, where t is the thickness of the shifter.

The phase of the same light wave traveling through air for a distance equal to t is Øa= 2ntλ-1.

We are supposed to derive an expression for the thickness of the shifter as a function of λ and n to get a phase shift of 180°.

Given, The phase of light of wavelength λ traveling through a shifter with a refractive index n is given by: Øs = 2πntλ-1

The phase of the same light wave traveling through air for a distance equal to t is Øa = 2ntλ-1

To obtain a phase shift of 180°, we have: Øs - Øa = πi where i is an integer.

Substituting the value of Øs and Øa in the above expression, we have:

2πntλ-1 - 2ntλ-1 = πi2πntλ-1 - 2ntλ-1

                         = π(2nλt) / λ2πntλ-1

                         = 2nλt / λπt

                         = λ / 2n

Hence, the thickness of the shifter is given as t = λ / 2n.

Kinetic energy is the energy that an object possesses due to its motion. Hence, the correct option is [109.5 J].

The formula to calculate kinetic energy is KE = 1/2 mv², where m is the mass of the object and v is its velocity or speed. In this question, the wagon wheel is a ring of mass 77.1 kg and radius 0.630 m. The wagon is moving at 1.22 m/s. We have to calculate the total kinetic energy of the wheel.The velocity of the wagon can be converted into the angular velocity of the wheel by using the formula v = wr. The angular velocity w is calculated as:w = v/rw = 1.22 m/s ÷ 0.630 m ≈ 1.936 rad/sNow that we know the angular velocity of the wheel, we can calculate its total kinetic energy using the formula KE = 1/2 Iw², where I is the moment of inertia of the wheel. For a ring-shaped object, the moment of inertia is given by I = mr².KE = 1/2 Iw²KE = 1/2 (mr²) (w²)KE = 1/2 (77.1 kg) (0.630 m)² (1.936 rad/s)²KE ≈ 109.5 J. Therefore, the total kinetic energy of the wagon wheel is approximately 109.5 J. Note: As per the question, the total kinetic energy of the wheel is required, not of the wagon.

To increase the view angle for the eye (camera), we increase the angle parameter in the projection matrix.

In computer graphics and computer vision, the projection matrix is used to transform 3D points in a scene to 2D points on a projection plane or image plane, simulating the perspective view of a camera or eye. The projection matrix incorporates various parameters, including the field of view (FOV) or view angle, which determines the extent of the scene that is visible in the rendered image.

The field of view or view angle is the angle that defines the extent of the scene that is visible from the camera or eye. It determines how much of the scene can be seen horizontally and vertically. A larger field of view or view angle results in a wider perspective and a broader view of the scene, while a smaller field of view or view angle results in a narrower perspective and a more zoomed-in view of the scene.

To increase the view angle for the eye (camera) in a computer graphics or computer vision application, we would need to increase the angle parameter in the projection matrix. This can be achieved by modifying the projection matrix parameters, such as changing the FOV or view angle value, to widen the field of view and increase the view angle of the camera or eye, resulting in a broader perspective of the scene.
